Ovarian cysts are very, very common and are almost always benign. They can cause a lot of problems, i.e. pain, nausea, bowel problems, bloating, etc. Usually they will resolve on their own, but if they don't and they continue to cause problems, there are treatments such as medications or surgery that will help.

seen the dr . have had 4 ultra sounds the cyst is low in left side, actually pain is on the right side. whole right side tender.
the cyst is tunneled from front to back . possible fluid but maybe solid . all have said you can't really see it from the us. it is clearer on the ct scan
ca 125 came back 6.7

that is good news.... right????
will see dr again in sept for more test.

It is rather strange that the ultrasound cannot see the cyst clearly, even if it is front to back. I know when I have my ultrasound he usually looks on my left side to see the side of the cyst as well as the frontal view. The wording of the report sounds very vague (liquid but could be solid ?! left adnexal mass which "could be" a cyst) as if the radiologist is trying to protect himself or something. The ultrasound should really say whether an ovarian cyst is liquid or solid and how thick the walls of the cyst are.

Perhaps an intravaginal ultrasound might be better in this case so they should send you for one of these. Indeed your CA-125 is normal so this is very encouraging (mine is at 7). The size of the cyst is also important and yours is average (I personally have a fluid filled ovarian cyst on my left ovary which is about 8 cm in diameter). The look of the cyst is very important (simple, complex etc..).

Yes although the cyst is on your left side you can experience pain on your right side. This is called referred pain. I sometimes experience pain on my right side. In my last ultrasound they mentioned that my cyst is pushing my uterus to the right and to the front so perhaps this may also have something to do with where the pain is being referred.
